Gold Flotation - 911 Metallurgist

13/07/2016  REAGENTS USED IN FLOTATION OF GOLD ORES. Conditioning agents are commonly used, especially when the ores are partly oxidized. Soda ash is the most widely used regulator of alkalinity. Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold.

Froth Flotation and Gold Extraction - Manhattan Gold

23/07/2014  In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a tank or flotation cell

Recovering Gold through the Froth Flotation Process ...

06/02/2018  However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Once the ore has been ground and a size distribution of particles is presented to a flotation cell, the only parameter that can be manipulated to reduce the entrainment is water recovery. If additional water is added to dilute the contents of the flotation cell, and the flow rate of water to the concentrate remains the same, the water recovery will

Silver Gold Recovery Flotation Process - 911 Metallurgist

17/10/2016  Between each stage are corduroy strakes on which free gold is recovered to the extent of 25% of the total gold content of the ore. Sodium aerofloat is added to the ball mills and thio-carbanilide to the tube mills. The discharge from the third grinding stage is pumped to a surge tank, pine oil being fed to the pump intake and aerofloat to the tank. Flotation is then carried out, as shown below, in three rows of ten-cell
